## Long description

Automatic air vent Valvex Alfa 1/2" model 4700230 is a compact valve intended for removal of trapped air in heating and plumbing systems. The valve features a 1/2" connection size and continuous automatic venting to support stable circulation, reduce noise and limit corrosion in closed-loop installations. It is suitable for use with radiators, boilers, pipelines and other domestic or light commercial systems where undesired air pockets impair performance.
Advantages
The Valvex Alfa automatic vent provides uninterrupted air discharge without manual intervention, minimizing downtime and maintenance. Its compact design allows installation in restricted spaces and on various system components. By promoting stable circulation and preventing air accumulation, the valve helps maintain system efficiency and reduces the risk of corrosion-related damage.
Suitable for
Radiator and convector installations in residential buildings
Domestic and small commercial boiler systems
Hot- and cold-water pipelines in closed-loop circuits
Hydronic heating manifolds and distribution headers
Key specifications
Connection size: 1/2" (internal/external thread as per installation requirement)
Function: continuous automatic air venting
Application: heating and plumbing systems, closed-loop hydronic circuits
Material: corrosion-resistant components suitable for contact with water-based heat transfer fluids
Design: compact form factor for installation in limited space locations
How to use
Install the automatic air vent in a vertical orientation at high points, radiators, or manifolds where air tends to accumulate, following system shut-down and depressurization procedures. Ensure threads are sealed with appropriate tape or sealant compatible with heating systems and that the valve is tightened to recommended torque levels. After installation, restore system pressure and check for leaks; the valve will automatically release trapped air during normal operation without further adjustment.
Usage recommendations
For reliable performance, place the valve at system high points and accessible locations to allow inspection and, if necessary, replacement. Periodically check for signs of leakage or malfunction during routine system maintenance. Use compatible sealing materials and avoid overtightening to prevent damage to threads or valve body.
